Right Shoulder Hurt

So, i have injured my right shoulder. I pulled a muscle and aggravated some kind of cushion between joints from what he said. The pain is awful and i can not used my right arm too painful. So, he has had me resting the last few days trying to get it healed. I will be glad when it is better. It has had me in tears the last few days from the pain. The only thing i can do is rest and not use my right arm until it heals. That is hard to do cause i am right handed but i am doing my best to not use it. I am hoping it will heal up soon.
